Washington SaaS Terms: A Drafting Checklist with Washington-Specific Overlays

SaaS terms of service are mostly a contract-drafting exercise: subscription mechanics, acceptable use, IP, warranty disclaimer, liability cap, dispute resolution. Washington adds three statutory overlays that any SaaS company selling into Washington should understand: the Consumer Protection Act in Chapter 19.86 RCW, the My Health My Data Act in Chapter 19.373 RCW, and the data breach notification statute in Chapter 19.255 RCW. This guide walks through the drafting checklist with the Washington overlays called out where they actually change the analysis.

Quick answer

A SaaS terms package selling into Washington should include solid baseline terms (subscription, auto-renewal, acceptable use, AI features, warranty disclaimer, liability cap, dispute resolution), and three Washington-specific overlays: a Consumer Protection Act risk review of marketing and auto-renewal practices, a My Health My Data Act analysis if the product touches any consumer health data, and an incident response plan tied to Chapter 19.255 RCW.

1. Subscription and auto-renewal

2. Acceptable use

3. Data processing

4. AI features

5. User uploads and content

6. Warranty disclaimers

7. Liability cap

8. Arbitration and dispute resolution

9. Venue and governing law

10. Privacy interaction

The terms of service should reference the privacy policy and any data processing addendum. Conflicts between the documents are a fertile source of litigation, so use cross-references and one canonical version for each topic.

Washington overlay 1: Consumer Protection Act (Chapter 19.86 RCW)

The Washington Consumer Protection Act, Chapter 19.86 RCW, prohibits unfair or deceptive acts or practices in the conduct of any trade or commerce. The private cause of action under allows a successful plaintiff to recover actual damages, treble damages up to a statutory cap, attorney fees, and an injunction. The five elements of the private CPA claim (per Washington case law applying ) are an unfair or deceptive act, in trade or commerce, that affects the public interest, causes injury to the plaintiff's business or property, and is causally linked.

For SaaS founders, the practical CPA exposures cluster around marketing claims that overstate features, hidden auto-renewal practices, dark-pattern cancellation flows, and material omissions in onboarding. The CPA is the enforcement vehicle the Washington Attorney General most often uses against consumer-facing SaaS practices, and it is also the private plaintiff's preferred theory because of the fee-shift and treble damages.

Washington overlay 2: My Health My Data Act (Chapter 19.373 RCW)

The Washington My Health My Data Act, Chapter 19.373 RCW, regulates the collection, use, sharing, and sale of consumer health data by regulated entities. It applies broadly to any consumer health data (not just HIPAA-covered data), and it covers a much wider universe of products than founders expect: wellness apps, fitness trackers, period and fertility trackers, mental health tools, AI symptom checkers, sleep apps, and any SaaS that infers health-related information from user inputs or device signals.

Key obligations under the Act include:

The private right of action through the CPA is the part most SaaS founders miss. A My Health My Data Act violation does not just trigger AG enforcement; it can also trigger CPA-style private litigation with fee-shifting and treble damages. If a product touches anything that could be characterized as health, wellness, fitness, mental health, or symptom-related data on Washington residents, this statute should be on the legal review list.

Washington overlay 3: Data breach notification (Chapter 19.255 RCW)

Washington's data breach notification statute, Chapter 19.255 RCW, imposes notification obligations when there is a breach of system security involving personal information of Washington residents. Key features that SaaS founders should bake into their incident response plan and customer contracts:
